24LC02B/P

Memory IC Overview

The Microchip Technology 24LC02B/P is a 2-Kbit (256 x 8) serial EEPROM housed in an 8-pin PDIP package. It operates on a single supply voltage ranging from 2.5V to 5.5V and supports I2C communication with a maximum clock frequency of 400 kHz. The device features a 900 ns access time and a 5 ms page write cycle. It is designed for industrial temperature ranges (-40°C to +85°C), offers over one million erase/write cycles, and retains data for more than 200 years.

Memory IC Feature Summary

• Supports bidirectional two-wire I2C compatible serial interface
• Includes hardware write-protect capability via the WP pin
• Features Schmitt trigger inputs for noise suppression
• Provides output slope control to eliminate ground bounce

Memory IC Applications

• Data logging systems requiring non-volatile storage
• Configuration memory for embedded controllers
• Parameter storage in industrial instrumentation
• Small data retention in consumer electronics

Memory IC Procurement Notes

Verify that the ordering suffix 'P' corresponds specifically to the 8-lead PDIP package type. Confirm the 'I' temperature grade matches the required -40°C to +85°C operating range. Ensure the voltage supply aligns with the 2.5V minimum requirement, as this variant does not support operation below 2.5V unlike other family members.

Memory IC Selection Notes

Select this component when through-hole mounting is required for prototyping or specific mechanical constraints. Choose the 24LC02B/P over surface mount variants if reworkability or manual assembly is prioritized. Note that the 2.5V minimum VCC distinguishes it from lower-voltage options like the 24AA02 series.

Memory IC Part Context

This part belongs to the 24XX02 family of 2-Kbit serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA02 and 24FC02 but differs in voltage specifications and clock speed capabilities. The PDIP package places it within the broader category of through-hole integrated circuits suitable for general-purpose digital memory applications.

Memory IC Replacement Considerations

Direct substitutes include other 24LC02B variants with different packages such as 24LC02B/SN (SOIC) or 24LC02B/MC (DFN). Cross-family replacements like 24AA02/P offer similar functionality but operate at lower voltages starting from 1.7V.
